NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation
is affected by absorption and reflection from objects, structures and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/
a
cordless) telephones and land mobile radios, amateur radio, AM and FM radio
broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess
the electromagnetic environment due to fixed RF transmitters, an electromagnetic site
survey should be considered. If the measured field strength in the location in which the
A S Temperature Management System unit is used exceeds the applicable
®
rctic un
RF compliance level above, the A
should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the
A S Temperature Management System unit.

Intended Electromagnetic Environment
Portable and mobile RF communications
equipment should be used no closer to
any part of the A S
®
rctic un
Management System unit, including cables,
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
d = 1.2√P
d = 1.2√P 80MHz to 800 MHz
d = 2.3√P 800MHz to 2.5GHz
where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufacturer
and d is the recommended minimum
separation distance in meters (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey , should be less than the compliance
a
level in each frequency range.

Recommended separation distances between portable and mobile RF
communications equipment and the A
System unit
RF communications equipment can effect medical electrical equipment. The
A S Temperature Management System unit is intended for use in an
®
rctic un
electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the A
can help prevent electromagnetic interference by maintaining a minimum distance
between the portable and mobile RF communications equipment (transmitters) and
the A S
rctic un
according to the maximum output power of the communications equipment.

equation applicable to the frequency of the transmitter, where P is the maximum
output power rating of the transmitter in watts (W) according to the transmitter
manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency
range applies.
